Our invention relates to a box which comprises a lower or receptacle portion made of a single' piece of corrugated breboard, solid breboard, paper board or any other similar material which can'be creased and folded or' rendered foldable in any manner, andk having corner portions whichv are folded on themselves and then folded along the sides of the box forming in veffect a tripled corner box, and a cover therefor made of a single piece of material such as de'- scribed above, with fold lines extending longi-v tudinally thereof whereby wing portions` areformed which are adapted to be tucked into channels along the sides of the box at the corners `Another and further object o f our invention is I the provision of a container which is substantial lin construction, easily and cheaply manufactured, and easily sealed to retain the top in position, and which provides a container-in which the cover may be detached entirely from lthe box or detached at one side of the box only sothat v the opposite side vacts as a hinge, the under side of the cover having advertising matter; thereon if desired, and which at the close of the day can be Aclosed over the container, thereby protecting the'contents of the box.

Another and further object of our invention is the provision'of a box which canbe shipped in at form and knock-down condition, and easily and quickly assembledat the plant or place of use, thereby resulting in a saving in freight rates,

quickness in handling, and the like, which is not possible to secure with boxes shipped in final completed form. l

These and other objects of the invention will be more fully and better understood by reference to the accompanying drawings, and in Figure 3 is a pen's'pective view' of thebox in' assembled relation, with the cover applied: e.

'Figure 8 is aplan view of a box blank of still another modified form of our improved inventiomald YFigure 9 is a perspective `view of a box and cover madeirom thefblank, illustrated in Figure '8 and the cover illustrated in Figure 2.

Referring now specically to the drawings and in which like reference characters referto like 20 parts throughout, theV receptacle or bottom portion of theybox is formedfrom a blank III, having Vlongitudinally extending foldrlines II and lI2 and'transverse fold lines I3 and I4 formed in the blank, Vwhereby .a bottom section I5, end 25 portions I6 and I1 are formed, and sideportions I 8 and I9. Corner portions 20, 2|, 22 and 23V are formed as an integral portionof the blank, II) 'and haveV the fold.lines II and I2 passing along 'one of their sides, the fold lines I3 and I I 30 passing along their ends.j In addition, diagonal fold lines 2l, 24 are provided which extend through the corner membersZIl, 2|, 2 2 and 23, and along which these corner portions are folded uponfth'emselves when the bottom or receptacle 35 portion of the box is formed.

`In. the form shown in Figure 1, the. corner portions and the ends are slightly less in length than the combined width of the bottom portion I5 and the side portions I8 and I9, while the fold o lines 24 passing in a diagonal direction across the corner portionsterminate in the sides of these corner portions a, short distance from the end, which produces vertically extending. edges 25, 25 on the corner portions when the lower' por- 45 tion of the box is formed, and in effect divides the corner sections into a triangular portion and a larger portion of irregular shape, and which is folded over the triangular vportion when the corners are secured to the sides-of the box. The 50 triangular section in effect forms a spacer for the outer section, the edgeof the cover. when placed in position, meeting the edge of the triangular section at its upper side.

In the formation of the receptacle or lower ,ff

sectional view` on 5 I portion of the box, the blank I9A is folded along the lines II and I2 and I8 and I4, so that the sides and endl portions are' in vertical position, and the corner sections 20, 2I 22 and 23 are at the same time folded upon themselves along the fold lines 24 and then turned alongside the side portions I8 and I9 of the box. Staples 28, 26 are inserted through the two thicknesses of the corner portions 20, 2I, 22 and 28and through the sidewalls I8 and I9 of the box, these staples being inserted at 'a point below the upper edge of the side portions I8 and I9, whereby the channelsare formed between the sides I8 and I9Aand the corners of the box 2 0, 2i, 22 and 23, for the reception of la lportion of the cover of the box, as hereinafter described, thereby forming triple corners in the box.

. The cover illustrated in Figure 2 is composed of a'single vfoldable piece of iibreboard, paper board or the like, having longitudinal fold lines 21 and 28, thereby. forming a cover 29 having wing Iportions 28 and '3L When the box is formed these wing portions 30 and 8| are turned downward along the fold lines 21 and 28 and in the channelsformed between the the upper edges of the ends I8 and I1 of thev box, thereby'completely covering the open'portion of the lower receptacle. 'If desired, av strip of gu'mmed paper or the like may be placed on .the ends of the cover portion and the sides of the ends i6 and I1 at their upper edges, effectively sealing 'the box against the admission of dirt, moisture or the like, and providing an easier lmeans for holding-the cover in Aposition for shipment, handling, and the like, although the frictional engagement of the-wing` portions of thev cover is suiilcient to hold -it in place for ordinary purposes.V 4

In Figure 6 a blank similar to that illustrated vin-Figure '1 isY shown, having longitudinally extending fold line's 32and 38 thereon, with trans'- versely extending fold lines 34 and 85 'whereby a gbottol'n 86, end portions 81 and 38 are formed,

with side portions 39 and 4|. Corner portions l 4I., 4I are-provided having diagonally extending fold lines 42 therein of thesame form and in substantially the samev position as shown in Figure 1, with projectingv portions 43 and 44 beingshown as extensions of the end portions and 88, and which inthe form of device shown vin assembled 'relation l(Figure '1), form iianges for the support of the cover 29. 'I'he projecting portions 48andV 44 also provide an additional seal at the end ofthe box to .prevent poibiiity Vof-moistur'e or the like entering under the edges of the cover, and a more ilrm sealing means for the cover than if the cover would'rest directly uponthe edges of the end portions oi' the lower container.

The assembling of the lower section of the' box is performed in exactly the same manner as that heretofore described with respectv to the formation and assembling or the blank illustrated ,in Figure 1, and forms a box which is exactly like that illustrated in Figure 3 except that it has the projections u. and u integrally formed with the ends for the purpose of supporting the cover as illustrated in Figure 2.

yIn Figure8va still further modiiled form is illustratedI this form being substantially like the forms illustrated in Figures 1 and 6 except that aioepov Y blank has longitudinally extending fold lines 46 and 41 therein, with transversely extending fold lines 48 and 49 forming the bottom section 50,

with ends 5I and 52 and sides 5I and 54, with corner portions 55, 55 being formed having diagonally extending fold lines 56, 56 extending thereacross from corner to corner and producing jin eiect pointed corner portions as shown particularly in the assembled relation of the box in Figure 9. In this form the entire corner section is bent outward slightly so the edge of the cover is inserted between the corner portions and the sides of the box after the corner portions are secured thereto.

The assembly of the'box is performed in exactly the same manner in that the box blank is folded along the longitudinal fold lines 49 and 41 and transversely extending fold lines 48 and 49, with the corners being folded diagonally and turned around alongside the sides 52 and 54 of the box and stapled by means of the staples 26, 26 at a point remote from the upper edge of the box, whereby a channel is formed for the reception ofthe wing portions I8 and Il o! the a unitary structure is formed comprising a lower or receptacle section and a cover therefor, of two blanks, and which when folded and assem- -bled is easily and quickly done, these blanks being quickly and easily assembled in the users plant, the blanks themselves being shipped in il'at form for the purpose of economy, ease'of handling, saving in freight rates and the like.

'While we have described more or less precisely the details of construction, we do not wish to be understood as limiting ourselves thereto, as we contemplate changes in form and lthe proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or the scope of our invention.
